Understanding the differences between tempered glass and ordinary (annealed) glass is essential for selecting the right material for your project. Here’s a brief overview of their key distinctions.

1. Manufacturing Process

Tempered Glass: This glass is heated to around 600°C (1100°F) and then rapidly cooled, enhancing its strength and thermal resistance. It is four to five times stronger than standard glass.

Annealed Glass: Produced through a simpler process, this glass is slowly cooled, making it weaker and more prone to breakage.

2. Strength and Safety

Tempered Glass: Known for its strength, it can withstand impacts and thermal stress. When broken, it shatters into small, blunt pieces, reducing injury risk.

Annealed Glass: More fragile, it breaks into sharp shards, posing a safety hazard, making it unsuitable for high-stress applications.

3. Thermal Resistance

Tempered Glass: It handles temperature fluctuations well, making it ideal for environments exposed to heat, such as shower doors and facades.

Annealed Glass: It has lower thermal resistance and is prone to breakage under sudden temperature changes.

4. Applications

Tempered Glass: Commonly used in shower enclosures, glass doors, facades, automotive glass, and furniture.

Annealed Glass: Typically used in picture frames, non-load-bearing windows, and decorative glass.

Conclusion

The differences between tempered glass and ordinary glass are significant, especially regarding strength and safety. For high-stress environments, tempered glass is the best choice, while annealed glass is suitable for less demanding applications.
